IMPROVEMENTI IN CARBURETING APPARATUS.

Specication forming part of Letters Patent No. 169,872, dated November 9, 1875; application led April 13, 1875.

To all whom it may concern:

Be it known that I, PELAG WERNl, of the city and county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Carbureting Apparatus; and I do hereby declare the following to be a clear and exact description of the nature thereof, sufficient to enable others skilled in the art to which my invention appertains to fully understand,make, and use the same, reference being had to the accompanying drawings making part of this specitication, in which- Figure l is a siderview of the device embodying ny invention. Fig. 2 is a transverse vertical section thereof. Fig. 3 is a face view of the mechanism bywhi'ch the pump is operated.

Similar letters of reference indicate corresponding parts in the several figures.

My invention relates to a gas apparatus; and the invention consists in a carbureter provided with an air-receiving and sediment or heavy-oil chamber, a carbureting-chamber, and a distributing-chamber, combined with an air-forcing pump and a pump for restoring the sediment or heavy oil to the carburetingchamber, substantially as hereinafter specified.

Referring to the drawings, A represents the carbureting-chamber,within which, at the upper and lower ends thereof, are arranged diaphragms B B', the lower one, B', of which leaves a space, O, between the same and bottom of the carbureting-chamber A. Within the chamber A, and resting on the lower diaphragm B', is a packing, D, formed of sawdust and sponge, which will absorb the hydrocarbon fluid placed in the chamber. E represents an air-pump or forcing apparatus, which communicates with the carbureting-'chamber A by means of a pipe, F, opening thereinto below the lower diaphragm B', so that air forced into said chamber will pass upward through the mass of hydrocarbon, and escape in a carbureted state through the pipe G to the place of usage or service. Communicating` with the space (l, by means of a valveopening, a, is a pump, H, whose cylinder has, at its upper end, an exit-pipe, J, which projects into the upper portion of the carbureting-chamber below the top diaphragm B. y

The hydrocarbon Huid is introduced into the chamber A through the feed -pipe b, or otherwise, and will be absorbed by the sponge and sawdust. Thepump E, being operated, forces air through the pipe F into the space G of the chamber A, and then through the hydrocarbon mass, which is suflciently dense to prevent the escape of air therethrough without being carbonized, and yet does not mate rially resist 'the passage of air. The carbureted air now lls the upper portion of the chamber A, and is directed through the pipe G to the place of service.

Some or all of the heavy oil or heavy inatters in the hydrocarbon will settle at the bottom ofthe chamber A, in the space (l, and the action of the pump H will take up said oil or matters and redeposit them, through. the pipe J, into the upper portion of the chamber A, where the air will again reach or act on them. In the event of lire, the upper diaphragm B will prevent the passage thereof into the mass of hydrocarbon duid below said diaphragm.

rlhe piston-rod b' of the pump is connected to a head, K, which has a vertical opening, d, on the inner face of whose walls there are formed teeth e e, which project toward each other, and with which engages a pinion, f,

whose surface is partly untoothed or plain. i

The axis of the pinion j'has its axial rod g on uprights h, mounted on the pump-cyllinder, or otherwise. On the outer faces of the head K there are secured plates L, which are slotted vertically, as at 7c, to permit passage ofthe head past the axial rod g of the pinion f, and the upper and lower portions of the slots 7c are curved laterally, as at m, for purposes to be explained'. The piston-rod of the heavyoil pump H is operated by a rocking arm or beam, which is connected to the head K.

The head K receives a reciprocating motion, and asthe teeth of the pinion fengage with the teeth e on one side of the opening d of the head K, they cause the head to rise, while the untoothed portion of the pinion moves freely past the teeth of the other side of said opening. Then, when the head has made its full motion, the pinion, rotating, en-

gages with the teeth e, from which it Was first disengaged, and eauses the descent of the head, the nntoothed portion of the pinion moving freely past the teeth e, with Which it was first engaged. When the engagement of the teeth of the pinion with the teeth ot' the opening is about to ooour, the axial pin g of the pinion moves in the lateral curves m of the slots 7c, and directs the pinion toward the toothed side of the opening With which it is to engage, and at the same time prevents the eXtreme ends of the said slot-s k reaching` the axial pin g, so that the return motions of the head are greatly eased.

`It Will also be seen that the slots 7c guide the head K, and, consequently, the piston-rod of the pump E, the motions of the rod being uniform and easy.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

Ina gas-machine, the combination of an airreceiving` chamber, C, oarbureting-ehamber D, distributing-chamber, air-forcing,` pump E, and pump H, the latter provided With a pipe, J, conducting therefrom to the chamber D, substantially as and for the purpose described.
